Use this activity to practice finding congruent triangles using appropriate theorems.
Students are given side lengths and angle measures for triangle ABC. They cut apart 8 triangles and try to decide if each one has enough information to prove it is congruent to triangle ABC. They sort each one based on the theorem: side side side, side angle side, angle side angle, angle angle side, or hypotenuse leg. Some triangles will not have enough information. Then they complete congruency statements.
Answer key is included.
